>Description:
Sometimes, the ATA driver will find drives that doesn't exist on my A7V
system. When this happens, I get the following error:
ata3-slave: ata_command: timeout waiting for intr
ata3-slave: identify failed
ata3-master: ata_command: timeout waiting for intr
ata3-master: identify failed

My A7V (board rev 1.02, BIOS 1005C) with Duron (800MHz) has a UDMA66 
drive on the Primary ATA100 (Promise, onboard) controller (only drive on
this cable) as master, and a DVD-ROM drive on the Secondary IDE
controller (only drive on this cable) as master.

On boot, I sometimes see the following:
[DVD-ROM/master]
atapci0: <VIA 82C686 ATA66 controller> port 0xd800-0xd80f at device 4.1 on pci0
ata1: at 0x170 irq 15 on atapci0
 .
 .
 .
atapci1: <Promise ATA100 controller> port 0x8800-0x883f,0x9000-0x9003,0x9400-0x9
407,0x9800-0x9803,0xa000-0xa007 mem 0xe2000000-0xe201ffff irq 10 at device 17.0 
on pci0
[Quantum Fireball Plus LM/master]
ata2: at 0xa000 on atapci1
[??]
ata3: at 0x9400 on atapci1

Sometimes, ata3 doesn't show up, but sometimes, it does. My current
ATA settings are all PIO. I have no cable dangling off the secondary
ATA100 connector.
